Multiple antenna system and method for mobile platforms
View Patent ↗A method and system facilitate communication between a constellation of satellites and a mobile platform-mounted mobile communicator. The method and system may include the use of a first antenna suited for operation using a first frequency band in a first geographic region and a second antenna suited for operation using either the first or a second frequency band in a second geographic region. The method and system may use a controller to determine which antenna to activate based on one or more of a geographic indicator or a signal indicator. The system used by the method to facilitate the communication may have one or more enclosures over the antennas and controller for mounting to a mobile platform.

determining, based on a geographic indicator, to terminate communicating data with the first satellite via the first subset of antennas and initiate communicating data with the first satellite or a second satellite using a second subset of antennas included in the plurality of antennas; and
controlling, using the controller, the second subset of antennas to communicate data with the first satellite or the second satellite.
12. The method of claim 11 , wherein the geographic indicator is indicative of at least one geographic characteristic of a mobile platform on which the platform-mounted mobile communicator is mounted, the at least one geographic characteristic corresponding to at least one of: (i) latitude and longitude coordinates, (ii) altitude, (iii) a current geographic region, (iv) a proximity to a boundary, (v) whether or not the boundary has been crossed, or (vi) another type of positional data.
